>6) A logo is often the property of someoene (individual, institution or
company) and/or is subject to legal usage restrictions (I cannot print the
recycled logo on new paper!), as opposed to writing systems, that are the
property of mankind and have no usage restrictions.

The Registered, Copyright and Trademark signs are also subject to legal
usage restrictions, but they have codepoints. The Recycled design is more
akin to that type of a mark than a logo. That is, it conveys an idea, not an
organization, a product or a service.
